It features a triangular insert shape with a 60-degree included angle and carries a multi-layer CVD coating of TiC, TiCN, and TiN for extended wear resistance and thermal stability. The inscribed circle measures 0.25 inches (1\/4 inch), insert length is 0.4331 inches (approximately 11 mm), and insert thickness is 0.125 inches (1\/8 inch). The corner radius is 0.016 inches (1\/64 inch). It is part of the HERTEL KENDEX series and is sold individually with a minimum order quantity of 10 units. Machinists and CNC operators working in production or job-shop environments install this insert type.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning applications on ferrous workpiece materials, with a primary material grade designation of P (steel) and a secondary designation of M (stainless steel). It is rated for a maximum depth of cut of 0.0492 inches (1.25 mm). The neutral hand orientation allows flexible use in both conventional and some specific tool holder configurations. It is commonly used in medium to finish turning passes where dimensional consistency and surface finish are priorities. The HC335 grade and C5\/C6 material grade classification make it appropriate for a range of steel and stainless turning conditions at moderate to higher cutting speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied TiC, TiCN, and TiN multilayer coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTriangular insert shape (60-degree included angle) with TPG221 style designation\u003c\/li\u003e\n  \u003cli\u003e0.016 inch corner radius suited for medium to finish turning passes\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible tool holder compatibility\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.0492 inches (1.25 mm)\u003c\/li\u003e\n  \u003cli\u003eClamp-type insert holding method with G tolerance and P clearance codes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement-style turning insert for TPG221 seat tool holders that accept triangular inserts with a 0.25 inch inscribed circle and clamp-style retention.

Ensure the tool holder pocket is clean and free of chips before seating the insert. Use the appropriate clamp torque per the tool holder manufacturer specifications and verify insert seating before resuming cutting operations. Follow shop safety procedures and applicable machine guarding standards when working near cutting tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPG221\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HC335\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4331 inches (11 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.016 inches (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiC, TiCN, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: P (Steel)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: M (Stainless Steel)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1001174\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738725548338,"sku":"1001174","price":240.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/470c667830937e7e5b96cd466716236d.jpg?v=1788803488","url":"https:\/\/voomisupply.com\/products\/hertel-1001174-turning-insert-tpg221-hc335-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
